This very special celebration of art in Mayfair and St James’s is in its third year and attracts people from around the world. Last year more than forty international museums sent representatives to visit the many treasures – paintings, drawings, sculpture and works of art – on view. As the selection of images here shows this year promises to be as good if not better.

The Crown Estate, who own about half of St James’s, are sponsoring the event. Their Head of the St James’s Portfolio, James Cooksey said: “The Crown Estate is delighted to support this important event in London’s art calendar which unites the art galleries of Mayfair and St. James’s, and helps to promote the extraordinary range of knowledge, expertise and heritage on offer in the art market’s historic home.”
